tZERO and BOX Digital Markets Sign Deal to Create Joint Venture

Expected to Become the World’s First Security Token Exchange

June 19, 2018, New York, NY -- tZERO and BOX Digital Markets LLC (“BOX Digital”) announced today they have entered into a joint venture, which is expected to become the world’s first regulated exchange for trading security tokens. Security tokens are electronic tokens defined as “securities” under U.S. law. The joint venture will seek approval from the U.S. Securities and Exchange Commission (SEC) prior to beginning operations.

tZERO will power the technology required to create and operate the JV. In addition, tZERO will manage the ongoing technology implementation, administration, maintenance and support. BOX Digital will provide executive leadership and regulatory expertise. Upon obtaining SEC approval, the joint venture will operate as a facility of BOX Options Exchange, an existing registered U.S. securities exchange.

Lisa Fall, CEO of BOX Digital, has been appointed as the new CEO of the joint venture. “We will work closely with the SEC to create a framework for the safe and efficient trading of security tokens and our joint venture with tZERO marks a significant step that brings us ever closer to creating the industry’s first regulated exchange for security tokens,” said Fall. “With BOX’s experience in building and operating a sophisticated equity options marketplace and tZERO’s industry leading blockchain technology, we have brought together our organizations’ combined expertise to create a more efficient capital market that will benefit traders and issuers.”

Last month, tZERO and BOX Digital entered into a letter of intent to negotiate an equal joint venture that would operate as a facility of the BOX Options Exchange for the trading of security tokens in the United States. Today’s announcement confirms the joint venture officially has been formed with tZERO and BOX Digital sharing economic ownership and board representation equally.

“There is no doubt that security tokens are the future of capital markets,” said Saum Noursalehi, CEO of tZERO. “tZERO and BOX Digital will create the first fully regulated security token exchange and fundamentally improve the way capital is raised and traded across different asset classes. Teaming up with Box Digital will allow us to complement our alternative trading system, already under development, with a separate, regulated platform, expanding the reach of our cutting-edge blockchain market technology to security token issuers of all types, from micro-cap issuers to SEC reporting companies.”

“I believe the greater investing community does not yet understand the extraordinary changes blockchain is going to bring to global capital markets. It is a great honor to have been selected by BOX as their partner for this historic endeavor,” added Patrick Byrne, CEO of Overstock.com and Executive Chairman on tZERO.
